Cold temperatures during the winter can bring extra headaches aside from drafty windows. Condensation on windows in the winter can point to several problems, and homeowners should take note if they discover window moisture this time of year.
When you have water condensation on your windows this winter, it’s not something to ignore. Consider the following advice about window moisture and condensation along with how to remove it.
What is Window Condensation?
Window condensation is moisture that forms on glass window panes. In some circumstances, condensation is perfectly normal. It forms when warm air comes in contact with a cool pane of glass, much like a glass of lemonade on a hot summer day.
From there, moisture forms on the glass. Condensation that wipes away is not a cause for concern. It will go away on its own or when you wipe it away with your hand.
The troubling part about condensation is when it forms inside the glass. If the condensation does not wipe away, it’s a sign of seal failure. This means that your windows are no longer performing properly and need to be replaced.
But what about condensation on windows during the winter? This is a different story.
How Does Condensation Happen?
When the outdoor temperatures drop, it creates temporary condensation. In fact, condensation is more likely to form when it’s really cold outside.
This is because the temperature surface of the inside glass drops. The condensation forms during cold days with lower relative humidity. Humidity is water vapor mixed with air, although cool air can’t hold as much moisture as warm air.
The reason why condensation forms on the windows first are because the glass is the coldest surface available. Surfaces that are cooler than room temperature are more likely to show humidity, so you will see water droplets on the glass.
Why Worry About Winter Window Condensation?
Condensation on windows in the winter is a little more concerning. That’s because window moisture inside during the winter can lead to a myriad of problems for your home and health.
Here’s why:
Excess Humidity
If the humidity levels in your home are too high, you can see window moisture inside during the winter. Excess humidity in the home can come from several sources, including your heating system, plants, and daily activities such as showering and dishwashing.
Too much humidity can even cause condensation to form on your walls. From there, the humidity continues to
Mold & Mildew Growth
One of the worst results of winter window condensation is mold and mildew growth. Mold can grow inside during the winter because it has access to a warm and humid environment. When it’s dark and there is a food source such as wood frames, mold will grow.
Peeling Interior Paint
When condensation manages to form on the walls, you might experience peeling paint. This is a sign that there is a prolonged moisture and humidity problem inside the home that must be corrected.
How to Correct Winter Window Condensation
Note that any windows can collect condensation. Even new windows!
Adjusting the humidity levels in your home can help, which is achieved by the following:
- Ventilate the room if you are cooking or showering
- Use a dehumidifier and exhaust fans as needed
- Vent your clothes dryer to go directly outside
- Reduce the amount of humidity-producing plants in your home, including spider plants, English ivy, and jade
- Consider the fact that heat rises, which can contribute to the natural process of humidity on top floor levels in a home
Aim to keep your home at humidity levels between 30% and 50%. This is considered ideal humidity for homes.
